What Causes Constipation And Swelling In The Eyes After Taking Antibiotics?

i have had an abscess an gingivitis for a kind of a long time so i took a 7 day cycle of antibiotics about three months ago and the symptoms stopped. then it started being bad again two weeks ago i had to go to the er just to get another ten day round of antibiotics that just ended five or six days ago. now i have constipation an what looks like an abscess in my eye swollen glands in my neck an pressure in my chest kind of by my collarbone. the problem is im out of my insurance coverage area and the e.r i went to out here they didn t seem to believe me about hearing fluid in my ears and pain around the ears an neck and didn t seem to think my glands were swollen. so i feel I got the wrong treatment. i just started taking echinacea tea and garlic and gargling salt water and taking Miralax for the constipation and un comfortability. do you have any idea what i have with all these symptoms and do you think i can get away with taking the home remedies for now till i can get to a doctor or i have a friend that has some antibiotics that they said i could have. any bit of help and knowledge you could shine on my situation would be great thank you
